The Pirates have optioned starter Tyler Glasnow and reliever Dovydas Neverauskas to Triple-A Indianapolis, MLB.com’s Adam Berry tweets. The idea, as Stephen J. Nesbitt of the Pittsburgh Post-Gazette tweets, is that Jameson Taillon will return and start on Monday, with Chad Kuhl pitching in Glasnow’s rotation spot on Wednesday. There’s no official word on who will Glasnow and Neverauskas on the roster in the short term, although the agent for righty reliever Edgar Santana recently tweeted congratulations to his client for making it to the big leagues for the first time.

Of these moves, the most newsworthy is Taillon’s quick return. Taillon had surgery for testicular cancer in early May and returned almost immediately, hopping back into baseball activities and then making three rehab starts in the high minors during which he showed little rust. That he will have been able to rejoin the Pirates’ rotation so quickly is heartwarming news after his shocking cancer diagnosis. Before his surgery, he had a 3.31 ERA, 7.6 K/9 and 3.3 BB/9 over 31 1/3 innings this season.

Glasnow, who once joined Taillon atop lists of the Pirates’ best pitching prospects, has struggled greatly this season, posting a 7.45 ERA, 8.3 K/9 and 4.8 BB/9 over 54 1/3 innings. The 23-year-old has size and elite stuff, with a mid-90s fastball and an excellent curveball, but he has made little evident progress in the development of his control.

Although towering right-hander Tyler Glasnow has gotten off to a slow start this year, the Pirates aren’t considering demoting the starter to Triple-A, writes Rob Biertempfel of the Pittsburgh Tribune-Review. While Clint Hurdle told Biertempfel that Glasnow must earn the right to stay in the majors, the manager is “a firm believer, as I believe everybody else is, that the greatest opportunity for growth is for him to pitch at this level and meet the challenges of the game at this level — and to understand the consequences of not being able to do the things you need to do at this level. You feel a lot more here than you do at Triple-A. There are games in the minors that nobody knows about. You don’t care. Up here, there’s a different care.” Glasnow had control problems in the minors last season, but the star prospect nevertheless dominated at Triple-A. The majors have been less forgiving for the 23-year-old, whose control issues haven’t dissipated since he debuted last season. So far this year, Glasnow has allowed nine earned runs on 10 hits and seven walks in 6 2/3 innings (two starts).

A few more notes from the National League…

Cardinals brass spent the offseason preaching defense, but Jose de Jesus Ortiz of the St. Louis Post-Dispatch wonders where the improvements are. The Redbirds rank among the majors’ bottom five in both errors (10) and Defensive Runs Saved (minus-14), and, in Ortiz’s estimation, have relied far too heavily on Matt Adams in left field (FanGraphs’ Dave Cameron echoed a similar sentiment Friday). Adams slimmed down during the winter, but he still entered the season as a first baseman with no outfield experience, which has been obvious to those who have watched the Cardinals in the early going.

The Diamondbacks’ usage of fledgling super-reliever Archie Bradley has been suboptimal thus far, Nick Piecoro of the Arizona Republic suggests. Bradley has been stellar out of the bullpen, having thrown 6 2/3 shutout innings and struck out 10 (against four hits and two walks), yet the Diamondbacks were on the wrong end of blowouts in two of his three appearances, as Piecoro points out. Manager Torey Lovullo has left open the possibility of Bradley becoming more of a high-leverage reliever, which makes sense for a team whose bullpen hasn’t been great. “We may change the inning based on what he’s doing,” Lovullo said. “We’re very well aware of what you’re saying. We know he’s had some quality outings and we want that to continue. It’s just going to be in any format possible to help us win a moment.”

Nationals shortstop Trea Turner, on the shelf since suffering a hamstring injury April 8, doesn’t expect his stay on the disabled list to last beyond the 10-day mark, per Jamal Collier of MLB.com. Turner could return as early as Wednesday, though that will depend on how he fares while testing out his hamstring before then. The speedster showed progress when he ran sprints, took batting practice and fielded grounders prior to the Nats’ game against the Phillies on Sunday. He’s one of two Washington shortstops dealing with hamstring injuries – Stephen Drew is the other – which has left the position in the hands of Wilmer Difo.

As Spring Training draws to a close, the final determinations about each team’s roster will be continue to come into focus. Here are some of the day’s more notable roster decisions…

Prized righty Tyler Glasnow will take the final spot in the Pirates rotation, Stephen Nesbitt of the Pittsburgh Post-Gazette reports on Twitter. He had been competing with Trevor Williams, who’ll head to the bullpen, Adam Berry of MLB.com adds on Twitter. With southpaw Wade LeBlanc also taking a job, that seems to set the stage for Rule 5 pick Tyler Webb to hit the waiver wire.

With injuries and young arms entering the picture, the Rockies’ pitching plans were interesting to watch this spring. As Nick Groke of the Denver Post tweets, the team will roll with lefty Kyle Freeland and righties Antonio Senzatela and German Marquez to fill out their starting staff. It seems likely that the former two will open the year in the rotation, with Marquez heading to the pen and staying on hand if a need arises.

Righty Oliver Drake has been named as the final member of the Orioles bullpen, Steve Melewski of MASNsports.com reports on Twitter. It had been suggested yesterday that Drake was placed on waivers, but it seems that was premature. Though he had a rough spring, Drake has shown an ability to induce lots of swings and misses with his deceptive pitch mix. The 30-year-old is out of options, so Baltimore had to carry him on the active roster to maintain control rights.

The Rangers made the surprising decision to option righty Keone Kela, as Jeff Wilson of the Fort Worth Star-Telegram tweets. Indications are that the move was related to off-field issues rather than performance questions or a need for roster space. Indeed, Kela was — and, perhaps, still is — expected to fulfill an important role in the Rangers’ pen. Though he dealt with elbow issues and struggled in the earned-run department last year, the 23-year-old was dominant this spring and seemed a good bet to bounce back.

Dennis Lin of the San Diego Union Tribune reports that Trevor Cahill and Luis Perdomo have won spots in the Padres’ rotation, thereby pushing Jarred Cosart to the bullpen. Cahill and Perdomo will be joined by Jhoulys Chacin, Jered Weaver and Clayton Richard in a reconstructed San Diego rotation that was pieced together in cost-effective fashion but still carries myriad question marks. Manager Andy Green didn’t rule out a return to the rotation or an eventual late-inning role for Cosart, but for the time being it sounds as if he’s slotted for long relief. Given the uncertainty that permeates the San Diego starting corps, that role could lead to plenty of innings for the 26-year-old Cosart early in the year.

The Yankees announced last night that right-hander Chad Green has been optioned to Triple-A Scranton/Wilkes-Barre. The 25-year-old Green had been in consideration for a rotation spot and turned in a strong 1.50 ERA in 12 spring innings, though that was accompanied by a less-encouraging 8-to-6 K/BB ratio. The Yankees aren’t planning to name a fifth starter before Opening Day and will utilize early off days to avoid needing a fifth starter for the early portion of April. Still, it’d be a surprise if Green didn’t at least enter the team’s rotation conversation at some point this season. For now, the team’s rotation will be comprised of Masahiro Tanaka, Michael Pineda, CC Sabathia and Luis Severino.

Jandel Gustave has won the Astros’ final bullpen spot, beating out fellow righty James Hoyt, per Jake Kaplan of the Houston Chronicle (Twitter link). The 24-year-old bounced to three different teams after being taken in the 2014 Rule 5 Draft before ultimately returning to the ’Stros. Gustave averaged 97.1 mph on his fastball in his brief MLB debut last season and turned in a 16-to-4 K/BB ratio in 15 1/3 innings of work.

Right-hander Austin Pruitt has beat out Chase Whitley and Jaime Schultz to make the Rays’ roster, reports Marc Topkin of the Tampa Bay Times. Injuries to Shawn Tolleson and Brad Boxberger likely helped to pave the way for Pruitt, 27, to break camp with the team. The 2013 ninth-round pick turned in a solid 3.76 ERA with 8.2 K/9 against 1.5 BB/9 in his first taste of Triple-A work last year. Manager Kevin Cash tells Topkin that delivering the news that Pruitt would make the Opening Day roster was “probably the best conversation all spring.” The manager also noted that a decision on the final bench slot may not come until Saturday (or even Sunday morning, Topkin adds via Twitter).

In an appearance on the podcast hosted by C. Trent Rosecrans and Zach Buchanan of the Cincinnati Enquirer, Reds president of baseball operations Dick Williams shared some interesting thoughts on his team and possible areas for innovation. (You can find a writeup of Williams’ comments and a link to the podcast right here.) Williams spoke in particular about the notion of “breaking down the barriers between roles,” both for pitchers and position players. Especially for a small-market team, he said, it’s necessary to question traditional thinking. While it’s hardly clear that the Reds will be tinkering just for the sake of experimentation — Williams says that creative approaches will be attempted “in the context of the talent we have coming” — he did note that it’s intriguing to imagine the possibility of a staff made up mostly of multi-inning pitchers who aren’t strictly classified as starters or relievers. It’s a fun and worthwhile listen.

Here’s more from the NL Central:

Cardinals GM John Mozeliak expressed some displeasure with recent comments from second baseman Kolten Wong, as ESPN.com’s Mark Saxon writes. Wong had stated rather forcefully that he was uninterested in sharing time at second — a possibility that has been discussed (externally, at least) due both to his continued struggles at the plate this spring and the presence of Jedd Gyorko. Though Wong softened his initial statement, making clear he wants to remain in St. Louis, Mozeliak said he felt the “comments were a little tough given the fact we have other players playing well.” The veteran executive took a measured tone, but made clear where the organization stands. “Starting Sunday, we’re playing to win,” he said. “Whenever a player is trying to accomplish something in spring training, that can’t be an excuse for why things aren’t going well.”

Righty Drew Hutchison was officially removed from the battle for the Pirates’ final rotation spot, with the team announcing that he has been optioned to Triple-A. That leaves righties Trevor Williams and Tyler Glasnow fighting for the fifth starter’s job. Both reached the majors last year after strong showings in the upper minors, though neither established himself at the game’s highest level. The young hurlers have each staked their claim in differing ways this spring, with Williams posting a 2.63 ERA with a dozen strikeouts against just two walks over 13 2/3 frames and Glasnow racking up 23 Ks — but also allowing nine runs on 19 hits and six free passes — over his 14 1/3 innings.

The 28-year-old Marte made his major league debut this year, throwing three and one-third scoreless innings but allowing two walks and five hits in that span while recording only a lone strikeout. He has converted to a relief role at Triple-A after previously working mostly as a starter, and carries a 3.67 ERA with 7.0 K/9 and 2.6 BB/9 over 73 2/3 frames there.

Partch, 29, was bombed in his two MLB appearances this year. But he was rather effective in his own stint at Indianapolis, compiling a 2.24 ERA in 60 1/3 frames. Partch notched sixty strikeouts in that span, though he also racked up thirty free passes.

The group of call-ups certainly holds some interest. Glasnow is the team’s highest-rated prospect, and he’ll return after making his debut earlier in the year. Trevor Williams has impressed at Triple-A despite lacking gaudy strikeout numbers. Florimon always seems to play a role somewhere in September, given his versatile glove.

And then there’s Hutchison, who was picked up in the somewhat controversial trade that sent Francisco Liriano (plus his contract) and two prospects to the Blue Jays at the trade deadline. The 26-year-old, who will be arbitration-eligible again next year, has worked to a 4.50 ERA in his 36 frames with Indy, with peripherals (7.0 K/9 against 3.8 BB/9) that fall shy of his work earlier this year at Buffalo.

The Rays believe there are roughly eight teams with strong enough farm systems to put together a package for right-hander Chris Archer in advance of the Aug. 1 non-waiver trade deadline, reports FOX Sports’ Ken Rosenthal (video link). One of those clubs, the Pirates, would have to move both righty Tyler Glasnow and outfield prospect Austin Meadows to acquire Archer. Glasnow, who’s currently in the midst of his second major league start, is sixth on Baseball America’s Midseason Top 100, while Meadows is 10th. Tampa Bay’s asking price is quite high, then, but Rosenthal notes that Archer has an eminently team-friendly contract through 2021. The soon-to-be 28-year-old has struggled to prevent runs this season and has seen both his walk and home run rates increase significantly, but he was a top-of-the-rotation option over 535 1/3 innings from 2013-15.

More deadline-related buzz from Rosenthal:

The remainder of the Royals’ current homestand (five games) will determine their course entering the deadline. At 48-47, the reigning World Series champions are eight games behind AL Central-leading Cleveland and five out of a Wild Card spot. Should they end up selling, free agents-to-be Edinson Volquez, Luke Hochevar and Kendrys Morales are all candidates to change uniforms. So is closer Wade Davis, whose contract expires after next season and whose demand around the league will only rise if the Yankees retain their late-inning relief aces. FanRag Sports’ Jon Heyman reported earlier Saturday that Washington is among the teams interested in Davis.

Nationals right-handed pitching prospect Erick Fedde could headline a package for Yankees closer Aroldis Chapman, and Rosenthal says landing the 23-year-old would be “a coup” for a team that covets young starters. Fedde, the 18th overall pick in the 2014 draft, is BA’s 61st-ranked prospect and has put up a 0.69 ERA in his last eight starts at the High-A level, per Rosenthal.

The thinness of the pitching market means it would make sense for the rebuilding Reds to listen to offers for righty Anthony DeSclafani, according to Rosenthal, who adds that the timing might not be right for Cincinnati to deal him. Given that DeSclafani is under club control through the end of the 2020 season, the Reds could build around him or keep him for now and hope his trade value continues increasing. The 26-year-old has been stellar this season, notching a 2.50 ERA, 7.15 K/9 and 1.61 BB/9 in 50 1/3 innings.

9:25am: Glasnow will actually debut tomorrow against the Cardinals, Olney now tweets. Rob Biertempfel of the Pittsburgh Tribune-Review tweets that Glasnow’s promotion was in part driven by uncertainty surrounding Niese’s left knee. Niese’s start has been pushed from Thursday to Sunday, and he’s being examined in Pittsburgh today.

8:39am: The Pirates will promote top prospect Tyler Glasnow to make a start this weekend against the Cubs, reports ESPN’s Buster Olney (via Twitter).

The 22-year-old Glasnow entered the season rated as a consensus top 15 prospect throughout the game and has worked to a 1.78 ERA through 96 innings at the Triple-A level this season. While he’s averaged 10.6 strikeouts per nine innings pitched in that time, he’s also averaged 4.9 walks per nine, so there are certainly some control issues that need to be further smoothed out. That high walk rate notwithstanding, Glasnow has yielded just 13 hits over his past 40 frames.

Entering the season, Baseball America rated Glasnow as the No. 14 prospect in baseball, writing that he featured a fastball that sits 94-96 mph but tops out at 99 mph and appears even faster than that to hitters due to his 6’8″ frame. Glasnow also offers a curve and a changeup, the former of which BA termed “unhittable when he has command of it.” MLB.com’s Jonathan Mayo and Jim Callis rated Glasnow as the No. 10 prospect and praised his clean delivery but noted that he struggles to consistently repeat it due to his size. ESPN’s Keith Law ranked him fourth on his midseason update of the game’s Top 25 prospects, calling him a future ace. Virtually any scouting report one can find on Glasnow agrees that his ceiling is that of a top-of-the-rotation starter, and the Pirates undoubtedly have visions of Glasnow and fellow top prospect Jameson Taillon joining current ace Gerrit Cole atop their rotation for the next several years in their perfect-world scenario.

Pittsburgh currently has Cole, Taillon and Ryan Vogelsong on the Major League disabled list, so the need for some rotation help is understandable. Those injuries, combined with struggles from veterans such as Francisco Liriano and Jon Niese, have led to season-long rotation problems. As such, the Bucs have had to dip into their farm system on multiple occasions to help patch things up; Pittsburgh received four good innings from left-hander Steven Brault in his big league debut yesterday and, and rookie right-hander Chad Kuhl has also made a pair of starts in the past week. The overall results for the starting staff haven’t been pretty, as Pirates starters rank 20th in the Majors with a 4.67 ERA and 21st with 464 innings thrown. Glasnow will become the 11th player to make a start for the team in 2016.

Innings don’t figure to be as significant of an issue with Glasnow as they are with Taillon, who didn’t pitch in 2014-15 due to injuries. However, Glasnow did total a fairly limited 109 1/3 innings last season between Double-A and Triple-A (an ankle injury cost him about a month of the season), and his career-high for innings pitched came back in 2014, when he totaled 143 2/3 frames between Class-A Advanced and the Arizona Fall League. As such, the Bucs will probably keep an eye on his workload moving forward.

Exactly how he factors into the rotation plans moving forward is yet unclear — this could be a spot start, or Glasnow could make regular starts with innings/pitch limits moving forward — but given the team’s injuries and the presence of Brault and Kuhl in the current rotation picture, it certainly seems possible that there’s a permanent spot to be won. If Glasnow is indeed in the Majors to stay, he’d be controllable through the 2022 season and would not be eligible for arbitration until after the 2019 season. He won’t sniff Super Two eligibility as it stands right now, as he’d finish the year with 87 days of Major League service time if he’s promoted on Friday and sticks through season’s end.

Athletics manager Bob Melvin thinks the trapezius problem that forced Sonny Gray to the disabled list Sunday is at the root of the right-hander’s early season woes. “It’s like pitching with a rock in the bottom of your neck,” Melvin said (Twitter link via Joe Stiglich of CSNBayArea.com). If Gray had been pitching through the injury before landing on the DL, it would explain his swift descent from an ace to one of the majors’ worst starters in 2016. For his part, Gray expects the DL stint to serve him and the team well. “It’s better to go ahead and try to miss a couple starts and knock this thing out. In the long run, it’ll benefit everyone,” he commented (Twitter link via Jane Lee of MLB.com).

Here’s more on a handful of other pitchers:

Newly signedAngels righty Tim Lincecum will head to Triple-A Salt Lake City at the end of the month and make at least two rehab starts there before joining the big league club, tweets Pedro Moura of the Los Angeles Times.

Pirates general manager Neal Huntington wants elite pitching prospects Tyler Glasnow and Jameson Taillon to spend the entire season with Triple-A Indianapolis, but he realizes that it’s unlikely to happen. “Perfect world they have a full year at Triple-A. It’s probably not going to be a perfect world,” he said Sunday (Twitter link via Travis Sawchik of the Pittsburgh Tribune Review). Glasnow and Taillon have torched the minors this year and look poised to join the Pirates when the Super Two threshold passes in June. Aside from Gerrit Cole and, to a much lesser extent, Juan Nicasio, Pittsburgh has gotten little production from its rotation members this year. Thus, Glasnow and Taillon will provide a pair of welcome reinforcements.

The Pirates have gotten many offers for minor league right-hander Chad Kuhl over the years, Huntington said Sunday (Twitter link via Stephen Nesbitt of the Pittsburgh Post-Gazette). Huntington added that he thinks Kuhl has the potential to be an asset in either the rotation or bullpen at the major league level. Both Glasnow and Taillon overshadow Kuhl, but the latter has gotten eye-opening results at Triple-A this year, posting a microscopic .99 ERA in 45 2/3 innings. Kuhl, 23, also demonstrated similar abilities at lower minor league levels.

Cardinals closer Trevor Rosenthal has struggled with command this month, walking nine batters in six innings, which manager Mike Matheny attributes to a lack of work. “If we see him take long breaks and then be really sharp when he comes in, that’s another story. But right now, he’s just not quite where he wants to be. And sometimes the only way of fixing that is to throw,” Matheny said (via Jenifer Langosch of MLB.com). Matheny plans to use Rosenthal more, even if it means the Cardinals deploy the 25-year-old so often that they have to rest him for certain save situations. “I think it’s probably the priority at this point to get [Rosenthal] the amount of work that he needs until he is right, and then build on that confidence,” Matheny stated.

Triple-A Pawtucket has placed Red Sox southpaw Brian Johnson on the temporary inactive list as he seeks treatment for anxiety, according to Ian Browne of MLB.com. Johnson, whom MLBpipeline.com ranks as Boston’s sixth-best prospect, will partake in “non-game baseball activities” in Fort Myers, Fla., while undergoing anxiety treatment. “Obviously we’re well aware of what he’s dealing with and we support him,” said manager John Farrell. “He’s a talented young guy and we’ll provide every available resource to him to get back to being a productive pitcher and a guy that we’d hope to factor in as we go forward.”

Coming into the season, Tyler Glasnow was expected to provide a mid-season boost to the Pirates rotation, and that looks likelier by the day. As MiLB.com’s Sam Dykstra writes, the young righty has been dominant at Triple-A and currently leads the International League in strikeout rate. Though a promotion seems all but inevitable at some point, the timing remains uncertain and may be dependent upon what the club can get from its current options (as well as its estimation of where the Super Two cutoff will fall). Jeff Locke is coming off of his best start of the year after some significant early struggles, while Juan Nicasio is throwing well enough currently to hold down another slot and Ryan Vogelsong remains a factor.

Here’s more from the National League …

The Mets may ultimately need to consider moving Travis d’Arnaud out from behind the plate, Ken Davidoff of the New York Post suggests. If d’Arnaud misses an extended stretch, argues Davidoff, the organization ought at least to think about alternatives to full-time catching. Of course, while the 27-year-old hit well enough last year (.268/.340/.485 in 268 plate appearances) to play anywhere on the diamond, he’s yet to carry that kind of production over even a full season and — regardless — is most valuable as a backstop.

Opposing pitchers have exhibited a new approach to breakout Rockies shortstop Trevor Story, Fangraphs’ Jeff Sullivan writes. After initially testing him on the inner half, with memorable results, hurlers are now attacking him away. While he’ll obviously have a chance to respond in the cat-and-mouse game, Story’s production has fallen off significantly. He still owns a rather productive .247/.306/.649 overall slash, but his 36.5% strikeout rate and recent lack of pull-side power opportunities certainly rate as concerns looking forward.

Barry Svrluga of the Washington Post questions the Nationals’ lack of action on GM Mike Rizzo’s contract. The veteran executive says he’s not yet heard anything, though he also expressed a lack of concern on the subject. While there’s no rush to decide on Rizzo’s two-year option (it’s due June 14), and expectations remain that he’ll remain with the organization, Svrluga says it remains a mystery why ownership hasn’t gone ahead and made a seemingly obvious decision to lock up club’s head baseball decisionmaker.

Andrew McCutchen reiterates that he’s interested in sticking with the Pirates, ESPN’s Jayson Stark reports. “[E]veryone knows I want to be here,” McCutchen says. “So that’s nothing new to anyone.” McCutchen has repeatedly maintained his interest in staying in Pittsburgh beyond the expiration of his contract following the 2018 season (or the 2017 season, in the unlikely event that the Bucs don’t exercise his 2018 option), and he’s also said he doesn’t define himself in terms of how much money he makes. According to Stark, though, McCutchen was cautious when asked whether he would take a hometown discount to stay with the Bucs. “I still stick with the [idea that] money doesn’t define me because it doesn’t,” he says. “But it’s not altered like that in this game. No one plays for free. People rarely ever work for free. But you know, whenever that time comes, that time comes. But I’m trying not to think about it too much.” The question, from the Pirates’ perspective, is whether there’s a way to extend McCutchen that makes sense within their budget. They already control him through his age-31 season, and they might not want to pay what the market would consider a fair salary for a player of McCutchen’s talent — surely over $20MM a year — for what could turn out to be decline years in his thirties. Here’s more on the Bucs.

Backup catcher Chris Stewart is happy to have received a multi-year deal this winter, MLB.com’s Adam Berry writes. Stewart’s deal was modest — he’ll get just $2.75MM total for 2016 and 2017, along with a $250K buyout on a cheap option in 2018. But it gives him more of a sense of stability than he’s previously had in his career. “Knowing that I’ll be here for more than a year — hopefully three or more, that’s the goal — that’s something I’m not used to,” he says. Stewart is slated to back up Francisco Cervelli in 2016, and then could back up Elias Diaz, a prospect with a good defensive reputation, in 2017 if Cervelli isn’t extended.

Top pitching prospect Tyler Glasnow appears likely to make an impact sometime in the coming season, but the Pirates also considered promoting him during the 2015 campaign, Rob Biertempfel of the Pittsburgh Tribune-Review writes. “We had legitimate discussions about (calling up) Tyler last year,” says Pirates GM Neal Huntington. “Ultimately, we felt it was in his and our best interest to continue the development and command of the fastball, the consistency of his breaking ball, the ability to throw it for a strike and for a chase, and to develop the changeup (in Triple-A).” He now seems likely to have to wait to be promoted until June, after the passing of the Super Two threshold. That’s what the Bucs did with Gerrit Cole three years ago, and Cole says it had no ill effects on him. “It’s actually better; you kind of light a fire under somebody,” Cole says “And he gets an opportunity to fine-tune his routine.”
